make your own : scout books
Although I've never tried them before, I have a generally good feeling about Pinball Publishing, the Portland, Oregon printshop that runs Scout Books. They offer a full range of offset printing services, but their Scout Books are a unique option.
You design your cover, and they'll have it printed on these pocketsize notebooks (3.5" x 5"). You can modify the specs by choosing a custom color as well as a filling of blank, lined or graph pages.
Print runs of these books come in quantities of 50 ($195), 100 ($305), 250 ($525), 500 ($650), 750($800) or 1000 ($975). I'm busy thinking up lots of ways to use these as gifts, promotion, party favors, valentines, you name it.
If you don't want to be bothered, there is a selection of pre-designed, ready-made Scout Books available as well.
